油菜素内酯是新发现的一种甾醇类激素,具有细胞分裂素的某些效应。我们以不同浓度BR试剂作了唐菖蒲切花的保鲜试验。供试材料为唐菖蒲属中的青骨红花(Gladiolus traderborn),油菜素内酯由日本提供,试剂浓度为10~0、10~(-1)、10~(-2)、10~(-3)、10~(-4)、10~(-5)ppm,以水为对照。从花圃切割唐菖蒲第一朵花刚开放的花枝,插入200毫升不同浓度的BR溶液中培养,隔日补充溶液,每种浓度选三枝花,重复三次,测定单花平均花期。
Brassinolide is a newly discovered steroid hormone that has some effect of cytokinin. We use different concentrations of BR reagent made gladiolus cut flowers preservation test. The tested materials were Gladiolus traderborn from Gladiolus, and the brassinolide was supplied from Japan at the concentrations of 10 ~ 0,10 ~ (-1), 10 ~ (-2), 10 ~ (-1) -3), 10 ~ (-4), 10 ~ (-5) ppm, water as control. Fresh flowering branches of the first gladiolus were cut from flower beds and inserted into 200 ml of BR solution of different concentrations. The solution was added every other day. Three flowers of each concentration were selected and repeated three times to determine the average flowering time of single flowers.
